Although I do not think this can be possible cause: I use Homebrew and python, qt and other gnu related files are installed with Homebrew. Could this cause this issue? That shouldn't be a problem provided that Audacity was installed from the official Audacity DMG (https://www.audacityteam.org/downl...

In Audacity 2.2.1 (which is available here if you don't already have it: https://www.audacityteam.org/download/), to convert a stereo track to mono: "Tracks menu > Mix > Mix Stereo down to Mono". The menu name describes what the function does - it mixes (combines by "adding") the...

Java is not one of my languages, and you've only given a fragment of code, so you'll have to help me out a bit here. Where does "freqOfTone" come from? Are you iterating over frequency values in "freqList" ? If so, are you simply concatenating the sounds from each "frequency...

For another example the difference between an E2 and an F2 is less than 5hz Yes, but the "Size" for FFT refers to the size of the analysis window in samples. At 44100 Hz sample rate, the maximum Size of 65536 samples is nearly 1 ½ seconds, so unless the musical tempo is very slow, the spe...

Have you tried the "Pitch Detect" plug-in?

Are you using an ancient version of Audacity? I recall some years ago that there was a bug that caused dither noise to be much higher than it should be.
Which version of Audacity are you using? (Look in "Help > About Audacity").

I want the greater accuracy for checking musical notes. I think one or two hz can be quite significant. Not if you only need to know what the note is. For example, with standard A440 tuning, an "A4" is nominally 440 Hz and an A#4 is about 466 Hz. If any real acoustic instrument plays an &...

I think that the frequency resolution for DFT will be basically proportional to the amount of data. Yes, the bigger the "Size" setting in Plot Spectrum, the smaller the "frequency bins" (narrower frequency bands), so the more precise the Hz measurements. At maximum "Size&qu...

Does anyone have a recommendation on a good digital mixer/recorder that can handle 6 to 8 mic inputs and a USB output to a laptop? I don't know if it is fully compatible with Audacity, but the Allen & Heath Qu-16 Chrome is an excellent mixer that meets those specifications: http://www.allen-hea...

So that we can give accurate and relevant information, please always say which exact version of Audacity you are using (look in "Help menu > About Audacity".) Assuming that you are using the current 2.2.1 version, look in "Transport menu > Transport Options > Sound Activated Recording...
